VMS Help RTL Routines, MTH$, BLAS1$VxASUM  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Obtain the Sum of the Absolute Values of the Elements of a
    Vector routine determines the sum of the absolute values of the
    elements of the n-element vector x.

    Format

      BLAS1$VSASUM  n ,x ,incx

      BLAS1$VDASUM  n ,x ,incx

      BLAS1$VGASUM  n ,x ,incx

      BLAS1$VSCASUM  n ,x ,incx

      BLAS1$VDZASUM  n ,x ,incx

      BLAS1$VGWASUM  n ,x ,incx

      Use BLAS1$VSASUM for single-precision real operations.
      Use BLAS1$VDASUM for double-precision real (D-floating)
      operations.
      Use BLAS1$VGASUM for double-precision real (G-floating)
      operations.

      Use BLAS1$VSCASUM for single-precision complex operations.
      Use BLAS1$VDZASUM for double-precision complex (D-floating)
      operations.
      Use BLAS1$VGWASUM for double-precision complex (G-floating)
      operations.
